83664-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83664-37-3 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 83664-37:
(7*8)+(6*3)+(5*6)+(4*6)+(3*4)+(2*3)+(1*7)=153
153 % 10 = 3
So 83664-37-3 is a valid CAS Registry Number.
