Check Digit Verification of cas no
The CAS Registry Mumber 197379-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197379-09:
(8*1)+(7*9)+(6*7)+(5*3)+(4*7)+(3*9)+(2*0)+(1*9)=192
192 % 10 = 2
So 197379-09-2 is a valid CAS Registry Number.
