1632156-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1632156-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,1,5 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1632156-33:
(9*1)+(8*6)+(7*3)+(6*2)+(5*1)+(4*5)+(3*6)+(2*3)+(1*3)=142
142 % 10 = 2
So 1632156-33-2 is a valid CAS Registry Number.
