Check Digit Verification of cas no
The CAS Registry Mumber 157685-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,6,8 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157685-26:
(8*1)+(7*5)+(6*7)+(5*6)+(4*8)+(3*5)+(2*2)+(1*6)=172
172 % 10 = 2
