764654-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 764654-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,4,6,5 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 764654-23:
(8*7)+(7*6)+(6*4)+(5*6)+(4*5)+(3*4)+(2*2)+(1*3)=191
191 % 10 = 1
So 764654-23-1 is a valid CAS Registry Number.
