Check Digit Verification of cas no
The CAS Registry Mumber 152110-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,1 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 152110-11:
(8*1)+(7*5)+(6*2)+(5*1)+(4*1)+(3*0)+(2*1)+(1*1)=67
67 % 10 = 7
So 152110-11-7 is a valid CAS Registry Number.
