Check Digit Verification of cas no
The CAS Registry Mumber 152972-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,7 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 152972-13:
(8*1)+(7*5)+(6*2)+(5*9)+(4*7)+(3*2)+(2*1)+(1*3)=139
139 % 10 = 9
So 152972-13-9 is a valid CAS Registry Number.
