Check Digit Verification of cas no
The CAS Registry Mumber 146981-04-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146981-04:
(8*1)+(7*4)+(6*6)+(5*9)+(4*8)+(3*1)+(2*0)+(1*4)=156
156 % 10 = 6
