Check Digit Verification of cas no
The CAS Registry Mumber 131947-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,4 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131947-97:
(8*1)+(7*3)+(6*1)+(5*9)+(4*4)+(3*7)+(2*9)+(1*7)=142
142 % 10 = 2
So 131947-97-2 is a valid CAS Registry Number.
