Check Digit Verification of cas no
The CAS Registry Mumber 229176-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,1,7 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 229176-14:
(8*2)+(7*2)+(6*9)+(5*1)+(4*7)+(3*6)+(2*1)+(1*4)=141
141 % 10 = 1
So 229176-14-1 is a valid CAS Registry Number.
