Check Digit Verification of cas no
The CAS Registry Mumber 152151-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,5 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 152151-54:
(8*1)+(7*5)+(6*2)+(5*1)+(4*5)+(3*1)+(2*5)+(1*4)=97
97 % 10 = 7
So 152151-54-7 is a valid CAS Registry Number.
