138748-57-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138748-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,4 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138748-57:
(8*1)+(7*3)+(6*8)+(5*7)+(4*4)+(3*8)+(2*5)+(1*7)=169
169 % 10 = 9
So 138748-57-9 is a valid CAS Registry Number.
