Check Digit Verification of cas no
The CAS Registry Mumber 857501-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,0 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 857501-37:
(8*8)+(7*5)+(6*7)+(5*5)+(4*0)+(3*1)+(2*3)+(1*7)=182
182 % 10 = 2
So 857501-37-2 is a valid CAS Registry Number.
