Check Digit Verification of cas no

The CAS Registry Mumber 15201-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,0 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 15201-70:
(7*1)+(6*5)+(5*2)+(4*0)+(3*1)+(2*7)+(1*0)=64
64 % 10 = 4
So 15201-70-4 is a valid CAS Registry Number.

The non-metathetic role of Grubbs' carbene complexes: From hydrogen-free reduction of α,β-unsaturated alkenes to solid-supported sequential cross-metathesis/reduction

Poeylaut-Palena, Andres A.,Testero, Sebastian A.,Mata, Ernesto G.

supporting information; experimental part, p. 1565 - 1567 (2011/03/20)

An efficient and high-yielding "hydrogen-free" reduction of α,β-unsaturated alkenes was carried out employing Grubbs' catalyst in a non-metathetic role and Et3SiH. Conditions were optimized under microwave irradiation. Application to the solid-phase organic synthesis allows a facile construction of sp3-sp3 carbon bonds through a sequential cross metathesis/olefin reduction.
