1203550-09-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1203550-09-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,5,5 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1203550-09:
(9*1)+(8*2)+(7*0)+(6*3)+(5*5)+(4*5)+(3*0)+(2*0)+(1*9)=97
97 % 10 = 7
So 1203550-09-7 is a valid CAS Registry Number.
