1229786-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1229786-45-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,7,8 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1229786-45:
(9*1)+(8*2)+(7*2)+(6*9)+(5*7)+(4*8)+(3*6)+(2*4)+(1*5)=191
191 % 10 = 1
So 1229786-45-1 is a valid CAS Registry Number.
