Check Digit Verification of cas no
The CAS Registry Mumber 93286-22-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,8 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93286-22:
(7*9)+(6*3)+(5*2)+(4*8)+(3*6)+(2*2)+(1*2)=147
147 % 10 = 7
So 93286-22-7 is a valid CAS Registry Number.
