39645-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39645-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,6,4 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39645-27:
(7*3)+(6*9)+(5*6)+(4*4)+(3*5)+(2*2)+(1*7)=147
147 % 10 = 7
So 39645-27-7 is a valid CAS Registry Number.
