1631962-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1631962-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,1,9,6 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1631962-34:
(9*1)+(8*6)+(7*3)+(6*1)+(5*9)+(4*6)+(3*2)+(2*3)+(1*4)=169
169 % 10 = 9
So 1631962-34-9 is a valid CAS Registry Number.
