Check Digit Verification of cas no
The CAS Registry Mumber 118972-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118972-97:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*2)+(2*9)+(1*7)=167
167 % 10 = 7
So 118972-97-7 is a valid CAS Registry Number.
