1279558-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1279558-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,9,5,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1279558-52:
(9*1)+(8*2)+(7*7)+(6*9)+(5*5)+(4*5)+(3*8)+(2*5)+(1*2)=209
209 % 10 = 9
So 1279558-52-9 is a valid CAS Registry Number.
