Check Digit Verification of cas no
The CAS Registry Mumber 134276-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,7 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134276-83:
(8*1)+(7*3)+(6*4)+(5*2)+(4*7)+(3*6)+(2*8)+(1*3)=128
128 % 10 = 8
So 134276-83-8 is a valid CAS Registry Number.
