136622-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136622-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,2 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136622-18:
(8*1)+(7*3)+(6*6)+(5*6)+(4*2)+(3*2)+(2*1)+(1*8)=119
119 % 10 = 9
So 136622-18-9 is a valid CAS Registry Number.
