Check Digit Verification of cas no
The CAS Registry Mumber 193286-32-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,2,8 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193286-32:
(8*1)+(7*9)+(6*3)+(5*2)+(4*8)+(3*6)+(2*3)+(1*2)=157
157 % 10 = 7
So 193286-32-7 is a valid CAS Registry Number.
