77971-33-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77971-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,7 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77971-33:
(7*7)+(6*7)+(5*9)+(4*7)+(3*1)+(2*3)+(1*3)=176
176 % 10 = 6
So 77971-33-6 is a valid CAS Registry Number.
