Check Digit Verification of cas no
The CAS Registry Mumber 1261975-01-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,9,7 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1261975-01:
(9*1)+(8*2)+(7*6)+(6*1)+(5*9)+(4*7)+(3*5)+(2*0)+(1*1)=162
162 % 10 = 2
So 1261975-01-2 is a valid CAS Registry Number.
