77150-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77150-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,5 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77150-72:
(7*7)+(6*7)+(5*1)+(4*5)+(3*0)+(2*7)+(1*2)=132
132 % 10 = 2
So 77150-72-2 is a valid CAS Registry Number.
