163812-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163812-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,1 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 163812-77:
(8*1)+(7*6)+(6*3)+(5*8)+(4*1)+(3*2)+(2*7)+(1*7)=139
139 % 10 = 9
So 163812-77-9 is a valid CAS Registry Number.
