51671-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 51671-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,7 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51671-50:
(7*5)+(6*1)+(5*6)+(4*7)+(3*1)+(2*5)+(1*0)=112
112 % 10 = 2
So 51671-50-2 is a valid CAS Registry Number.
