Check Digit Verification of cas no
The CAS Registry Mumber 333399-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,9 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 333399-49:
(8*3)+(7*3)+(6*3)+(5*3)+(4*9)+(3*9)+(2*4)+(1*9)=158
158 % 10 = 8
