Check Digit Verification of cas no
The CAS Registry Mumber 305357-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,3,5 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 305357-79:
(8*3)+(7*0)+(6*5)+(5*3)+(4*5)+(3*7)+(2*7)+(1*9)=133
133 % 10 = 3
