83664-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83664-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,6 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83664-31:
(7*8)+(6*3)+(5*6)+(4*6)+(3*4)+(2*3)+(1*1)=147
147 % 10 = 7
So 83664-31-7 is a valid CAS Registry Number.
