Check Digit Verification of cas no
The CAS Registry Mumber 157797-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,9 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157797-26:
(8*1)+(7*5)+(6*7)+(5*7)+(4*9)+(3*7)+(2*2)+(1*6)=187
187 % 10 = 7
