Check Digit Verification of cas no
The CAS Registry Mumber 168976-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,9,7 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 168976-37:
(8*1)+(7*6)+(6*8)+(5*9)+(4*7)+(3*6)+(2*3)+(1*7)=202
202 % 10 = 2
So 168976-37-2 is a valid CAS Registry Number.
