1229786-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1229786-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,7,8 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229786-69:
(9*1)+(8*2)+(7*2)+(6*9)+(5*7)+(4*8)+(3*6)+(2*6)+(1*9)=199
199 % 10 = 9
So 1229786-69-9 is a valid CAS Registry Number.
