77901-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77901-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,0 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77901-40:
(7*7)+(6*7)+(5*9)+(4*0)+(3*1)+(2*4)+(1*0)=147
147 % 10 = 7
So 77901-40-7 is a valid CAS Registry Number.
