63737-46-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63737-46-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,7,3 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63737-46:
(7*6)+(6*3)+(5*7)+(4*3)+(3*7)+(2*4)+(1*6)=142
142 % 10 = 2
So 63737-46-2 is a valid CAS Registry Number.
