401516-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 401516-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,5,1 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 401516-52:
(8*4)+(7*0)+(6*1)+(5*5)+(4*1)+(3*6)+(2*5)+(1*2)=97
97 % 10 = 7
So 401516-52-7 is a valid CAS Registry Number.
