331268-82-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331268-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,2,6 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 331268-82:
(8*3)+(7*3)+(6*1)+(5*2)+(4*6)+(3*8)+(2*8)+(1*2)=127
127 % 10 = 7
So 331268-82-7 is a valid CAS Registry Number.
