Check Digit Verification of cas no

The CAS Registry Mumber 1335545-32-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,5,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1335545-32:
(9*1)+(8*3)+(7*3)+(6*5)+(5*5)+(4*4)+(3*5)+(2*3)+(1*2)=148
148 % 10 = 8
So 1335545-32-8 is a valid CAS Registry Number.

Lipase catalyzed resolution of the quaternary stereogenic center in ketone-derived benzo-fused cyclic cyanohydrins

Rodriguez-Rodriguez, Jesus A.,Gotor, Vicente,Brieva, Rosario

, p. 1218 - 1224 (2011)

The enantioselective preparation of both enantiomers of the benzo-fused cyanohydrin derived from atetralone via lipase catalyzed processes is described. The (S)-enantiomer has been obtained as the remaining substrate in the CAL-A catalyzed aminolysis of the methoxyacetylated derivative, using a structurally related amine as the nucleophile. The (R)-enantiomer has been obtained as the product of CAL-A or PSL-C catalyzed hydrolysis of the methoxyacetylated derivative in organic solvents. The resolutions of several structural analogs of this cyanohydrin have been also tested under similar conditions.
