Check Digit Verification of cas no
The CAS Registry Mumber 132923-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,2 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132923-38:
(8*1)+(7*3)+(6*2)+(5*9)+(4*2)+(3*3)+(2*3)+(1*8)=117
117 % 10 = 7
So 132923-38-7 is a valid CAS Registry Number.
