1262887-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262887-91-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,8 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1262887-91:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*8)+(3*7)+(2*9)+(1*1)=191
191 % 10 = 1
So 1262887-91-1 is a valid CAS Registry Number.
