Check Digit Verification of cas no
The CAS Registry Mumber 138912-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,1 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138912-49:
(8*1)+(7*3)+(6*8)+(5*9)+(4*1)+(3*2)+(2*4)+(1*9)=149
149 % 10 = 9
So 138912-49-9 is a valid CAS Registry Number.
