Check Digit Verification of cas no
The CAS Registry Mumber 115961-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,6 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 115961-12:
(8*1)+(7*1)+(6*5)+(5*9)+(4*6)+(3*1)+(2*1)+(1*2)=121
121 % 10 = 1
So 115961-12-1 is a valid CAS Registry Number.
