77747-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77747-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,4 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77747-70:
(7*7)+(6*7)+(5*7)+(4*4)+(3*7)+(2*7)+(1*0)=177
177 % 10 = 7
So 77747-70-7 is a valid CAS Registry Number.
