628297-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 628297-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,8,2,9 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 628297-94:
(8*6)+(7*2)+(6*8)+(5*2)+(4*9)+(3*7)+(2*9)+(1*4)=199
199 % 10 = 9
So 628297-94-9 is a valid CAS Registry Number.
