916991-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916991-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,9,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 916991-51:
(8*9)+(7*1)+(6*6)+(5*9)+(4*9)+(3*1)+(2*5)+(1*1)=210
210 % 10 = 0
So 916991-51-0 is a valid CAS Registry Number.
