877776-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877776-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,7,7 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 877776-23:
(8*8)+(7*7)+(6*7)+(5*7)+(4*7)+(3*6)+(2*2)+(1*3)=243
243 % 10 = 3
So 877776-23-3 is a valid CAS Registry Number.
