72629-61-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72629-61-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72629-61:
(7*7)+(6*2)+(5*6)+(4*2)+(3*9)+(2*6)+(1*1)=139
139 % 10 = 9
So 72629-61-9 is a valid CAS Registry Number.
