Check Digit Verification of cas no
The CAS Registry Mumber 173963-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,9,6 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173963-92:
(8*1)+(7*7)+(6*3)+(5*9)+(4*6)+(3*3)+(2*9)+(1*2)=173
173 % 10 = 3
