Check Digit Verification of cas no
The CAS Registry Mumber 521274-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,2,7 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 521274-33:
(8*5)+(7*2)+(6*1)+(5*2)+(4*7)+(3*4)+(2*3)+(1*3)=119
119 % 10 = 9
