Check Digit Verification of cas no
The CAS Registry Mumber 132776-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,7 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132776-21:
(8*1)+(7*3)+(6*2)+(5*7)+(4*7)+(3*6)+(2*2)+(1*1)=127
127 % 10 = 7
So 132776-21-7 is a valid CAS Registry Number.
