74627-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74627-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,2 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74627-61:
(7*7)+(6*4)+(5*6)+(4*2)+(3*7)+(2*6)+(1*1)=145
145 % 10 = 5
So 74627-61-5 is a valid CAS Registry Number.
