629645-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 629645-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,9,6,4 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 629645-80:
(8*6)+(7*2)+(6*9)+(5*6)+(4*4)+(3*5)+(2*8)+(1*0)=193
193 % 10 = 3
So 629645-80-3 is a valid CAS Registry Number.
