Check Digit Verification of cas no
The CAS Registry Mumber 197243-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,2,4 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197243-61:
(8*1)+(7*9)+(6*7)+(5*2)+(4*4)+(3*3)+(2*6)+(1*1)=161
161 % 10 = 1
So 197243-61-1 is a valid CAS Registry Number.
