229977-68-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229977-68-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,9,7 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 229977-68:
(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*7)+(2*6)+(1*8)=198
198 % 10 = 8
So 229977-68-8 is a valid CAS Registry Number.
