1283716-39-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283716-39-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,7,1 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1283716-39:
(9*1)+(8*2)+(7*8)+(6*3)+(5*7)+(4*1)+(3*6)+(2*3)+(1*9)=171
171 % 10 = 1
So 1283716-39-1 is a valid CAS Registry Number.
