1551-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1551-74-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1551-74:
(6*1)+(5*5)+(4*5)+(3*1)+(2*7)+(1*4)=72
72 % 10 = 2
So 1551-74-2 is a valid CAS Registry Number.
