Check Digit Verification of cas no

The CAS Registry Mumber 72050-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,5 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72050-05:
(7*7)+(6*2)+(5*0)+(4*5)+(3*0)+(2*0)+(1*5)=86
86 % 10 = 6
So 72050-05-6 is a valid CAS Registry Number.

Triphenylphosphine Decomposition of Sulfenyl Thiocarbonates

Harpp, David N.,Granata, Alessandro

, p. 271 - 273 (2007/10/02)

Several sulfenyl thiocarbonates (RSSCO2CH3) have been decomposed with triphenylphosphine.In the case of R = alkyl, desulfurization takes place to give the S-alkyl thiocarbonate while in the case of R = aryl, a phosphonium salt is likely formed which on chromatographic workup on silica gel is converted to a thiol and triphenylphosphine oxide and sulfide.A mechanistic interpretation is offered.
