77901-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77901-39-4 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, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77901-39:
(7*7)+(6*7)+(5*9)+(4*0)+(3*1)+(2*3)+(1*9)=154
154 % 10 = 4
So 77901-39-4 is a valid CAS Registry Number.
