Check Digit Verification of cas no
The CAS Registry Mumber 132783-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,8 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132783-27:
(8*1)+(7*3)+(6*2)+(5*7)+(4*8)+(3*3)+(2*2)+(1*7)=128
128 % 10 = 8
So 132783-27-8 is a valid CAS Registry Number.
