952671-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 952671-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,6,7 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 952671-16:
(8*9)+(7*5)+(6*2)+(5*6)+(4*7)+(3*1)+(2*1)+(1*6)=188
188 % 10 = 8
So 952671-16-8 is a valid CAS Registry Number.
