137104-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137104-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,0 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137104-63:
(8*1)+(7*3)+(6*7)+(5*1)+(4*0)+(3*4)+(2*6)+(1*3)=103
103 % 10 = 3
So 137104-63-3 is a valid CAS Registry Number.
