Check Digit Verification of cas no
The CAS Registry Mumber 138824-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,2 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138824-97:
(8*1)+(7*3)+(6*8)+(5*8)+(4*2)+(3*4)+(2*9)+(1*7)=162
162 % 10 = 2
So 138824-97-2 is a valid CAS Registry Number.
