77202-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77202-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,0 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77202-93:
(7*7)+(6*7)+(5*2)+(4*0)+(3*2)+(2*9)+(1*3)=128
128 % 10 = 8
So 77202-93-8 is a valid CAS Registry Number.
