3742-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3742-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,4 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.Calculate Digit Verification of CAS Registry Number 3742-38:
(6*3)+(5*7)+(4*4)+(3*2)+(2*3)+(1*8)=89
89 % 10 = 9
So 3742-38-9 is a valid CAS Registry Number.
