Check Digit Verification of cas no
The CAS Registry Mumber 12236-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12236-92:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*9)+(1*2)=79
79 % 10 = 9
So 12236-92-9 is a valid CAS Registry Number.
