Check Digit Verification of cas no
The CAS Registry Mumber 132861-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,6 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132861-67:
(8*1)+(7*3)+(6*2)+(5*8)+(4*6)+(3*1)+(2*6)+(1*7)=127
127 % 10 = 7
So 132861-67-7 is a valid CAS Registry Number.
