74274-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74274-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,7 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74274-38:
(7*7)+(6*4)+(5*2)+(4*7)+(3*4)+(2*3)+(1*8)=137
137 % 10 = 7
So 74274-38-7 is a valid CAS Registry Number.
