Check Digit Verification of cas no
The CAS Registry Mumber 133590-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133590-12:
(8*1)+(7*3)+(6*3)+(5*5)+(4*9)+(3*0)+(2*1)+(1*2)=112
112 % 10 = 2
