Check Digit Verification of cas no
The CAS Registry Mumber 1198351-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,3,5 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1198351-56:
(9*1)+(8*1)+(7*9)+(6*8)+(5*3)+(4*5)+(3*1)+(2*5)+(1*6)=182
182 % 10 = 2
So 1198351-56-2 is a valid CAS Registry Number.
