1283752-22-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283752-22-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,7,5 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1283752-22:
(9*1)+(8*2)+(7*8)+(6*3)+(5*7)+(4*5)+(3*2)+(2*2)+(1*2)=166
166 % 10 = 6
So 1283752-22-6 is a valid CAS Registry Number.
