Check Digit Verification of cas no
The CAS Registry Mumber 37953-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,5 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.Calculate Digit Verification of CAS Registry Number 37953-05:
(7*3)+(6*7)+(5*9)+(4*5)+(3*3)+(2*0)+(1*5)=142
142 % 10 = 2
So 37953-05-2 is a valid CAS Registry Number.
