138536-72-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138536-72-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138536-72:
(8*1)+(7*3)+(6*8)+(5*5)+(4*3)+(3*6)+(2*7)+(1*2)=148
148 % 10 = 8
So 138536-72-8 is a valid CAS Registry Number.
