Check Digit Verification of cas no
The CAS Registry Mumber 155682-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,8 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155682-73:
(8*1)+(7*5)+(6*5)+(5*6)+(4*8)+(3*2)+(2*7)+(1*3)=158
158 % 10 = 8
