Check Digit Verification of cas no
The CAS Registry Mumber 37632-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,6,3 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37632-18:
(7*3)+(6*7)+(5*6)+(4*3)+(3*2)+(2*1)+(1*8)=121
121 % 10 = 1
So 37632-18-1 is a valid CAS Registry Number.
