156963-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156963-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,6 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156963-21:
(8*1)+(7*5)+(6*6)+(5*9)+(4*6)+(3*3)+(2*2)+(1*1)=162
162 % 10 = 2
So 156963-21-2 is a valid CAS Registry Number.
