Check Digit Verification of cas no
The CAS Registry Mumber 151153-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,1,5 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 151153-52:
(8*1)+(7*5)+(6*1)+(5*1)+(4*5)+(3*3)+(2*5)+(1*2)=95
95 % 10 = 5
So 151153-52-5 is a valid CAS Registry Number.

SYNTHESIS OF 1-H-THIOPHTHALYLIUM SALTS AND THEIR ELECTROPHILIC CHARACTERISTICS
Oparin, D. A.,Khodorkovskii, V. Yu.
, p. 141 - 149 (2007/10/02)
A convenient preparative method was developed for the synthesis of 1-H-thiophthalylium salts, including reduction of 1-alkylthio-substituted thiophthalylium tetrafluoroborates with sodium borohydride in anhydrous methanol and reaction of the obtained thio
