74275-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74275-08-4 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 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74275-08:
(7*7)+(6*4)+(5*2)+(4*7)+(3*5)+(2*0)+(1*8)=134
