645394-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 645394-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,5,3,9 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 645394-74:
(8*6)+(7*4)+(6*5)+(5*3)+(4*9)+(3*4)+(2*7)+(1*4)=187
187 % 10 = 7
So 645394-74-7 is a valid CAS Registry Number.
