123731-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123731-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,3 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123731-37:
(8*1)+(7*2)+(6*3)+(5*7)+(4*3)+(3*1)+(2*3)+(1*7)=103
103 % 10 = 3
So 123731-37-3 is a valid CAS Registry Number.
