137344-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137344-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137344-74:
(8*1)+(7*3)+(6*7)+(5*3)+(4*4)+(3*4)+(2*7)+(1*4)=132
132 % 10 = 2
So 137344-74-2 is a valid CAS Registry Number.
