71764-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71764-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,6 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71764-12:
(7*7)+(6*1)+(5*7)+(4*6)+(3*4)+(2*1)+(1*2)=130
130 % 10 = 0
So 71764-12-0 is a valid CAS Registry Number.
