Check Digit Verification of cas no
The CAS Registry Mumber 132794-07-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,9 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132794-07:
(8*1)+(7*3)+(6*2)+(5*7)+(4*9)+(3*4)+(2*0)+(1*7)=131
131 % 10 = 1
So 132794-07-1 is a valid CAS Registry Number.
