229975-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229975-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,9,7 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 229975-13:
(8*2)+(7*2)+(6*9)+(5*9)+(4*7)+(3*5)+(2*1)+(1*3)=177
177 % 10 = 7
So 229975-13-7 is a valid CAS Registry Number.
