39739-08-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39739-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39739-08:
(7*3)+(6*9)+(5*7)+(4*3)+(3*9)+(2*0)+(1*8)=157
157 % 10 = 7
So 39739-08-7 is a valid CAS Registry Number.
