Check Digit Verification of cas no
The CAS Registry Mumber 135221-23-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,2 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135221-23:
(8*1)+(7*3)+(6*5)+(5*2)+(4*2)+(3*1)+(2*2)+(1*3)=87
87 % 10 = 7
